Behaviour of rubber seals at low temperatures. Results of component tests

In this work thermo-analytical methods (Differential Scanning Calorimetry (DSC), Dynamic Mechanical Analysis (DMA), and Thermo Mechanical Analysis (TMA)) were applied to determine characteristic temperature values that characterize the glass-rubber transition. These values were compared with the findings of the component tests. A model was developed to describe the observed differences between thermal analysis and the behaviour under purely static stress conditions. (orig.)
